The conclusions are misguided to say the least and it’s extremely clear the authors have an agenda to push but some of the facts are indeed true.
If you look at lifetime data, BEVs do not save all that much in GHG emissions. About 30% in the German energy mix. Technologically, that’s an amazing leap in efficiency but not even close to getting us carbon-neutral because the reference (ICE) is extremely bad. “Less extremely bad” is not “good”.
The conclusion they come to that we should therefore be buying more “efficient” ICE cars instead is laughably stupid as I’m sure everyone here knows but the current “strategy” (if you can call it that) of “converting” every current ICE to a BEV will not solve the problem either. That’ll get us maybe 30-40% of the way there, probably less.
The future of transport is less cars, not cars but with different motors. And with less, I don’t mean a little less, I mean a fraction of what we have today.
The small fraction of cars left should ideally be BEVs but it wouldn’t make a huge difference in absolute terms at that point and shouldn’t be the focus of any discussion of future transport.
